How to include temperture and pressure dependend material data in CFX

Maximilian87 · October 21, 2015, 09:15

I want to include material data of air (thermal / electrical cunductivity, viscosity, ...), which is both temperature and pressure dependent (2 interpolations are needed). I alredy figured out how to do it with only one dependency and using CEL, but I can't find any suggestions to do it with two dependencies. I have the material data as a text file. Is there any easier function than using Fortran routines?

thank you very much for your help

Have you tried using a temperature, pressure profile ?

[Name]
MyProperties

[Data]
Temperature [K], Pressure [Pa], Electrical Conductivity [S], ...
300, 1E+05, 0.001, ...
...

Then initialize the profile ?
